GTE Distributed Object Computing Group: Technical Reports

Technical Reports from
The Distributed Object Computing Group
GTE Laboratories Incorporated

Waltham, Massachusetts 02254, USA

On June 30, 2000 GTE Corporation and Bell Atlantic Corporation merged to form Verizon Communications. At that time GTE Laboratories was merged into the Bell Atlantic Technology Organization to form Verizon Laboratories.

The Distributed Object Computing Group existed in GTE Laboratories from fall 1987 until the fall of 1995. For most of that time the group was headed by Dr. Michael L. Brodie with principal researchers: Frank Manola, Sandra Heiler, Dimitrios Georgakopoulos, Alejandro P. Buchmann, Gail Mitchell, and Jennifer L. Welch. Visiting scientists included Peter C. Lockemann, Cris Pedregal Martin, M. Tamer ?zsu, Ole J. Anfindsen, and Daniel Rios-Zertuche. The experimental researchers included Dinesh K. Desai, Mark F. Hornick, Benjamin Hurwitz, Piotr Krychniak, Joe D. Morrison, Emon Mortazavi, Farshad Nayeri, and Vivek Virmani with part time members Jintae Lee, Himanshu Sinha, Eric Wiseblatt, and Kay Chang.

The primary focus of the Distributed Object Computing Group within GTE Laboratories was the Distributed Object Management (DOM) project. The DOM project conducted research into object-oriented technology for integrating heterogeneous, autonomous, distributed (HAD) computer systems/resources. Major research areas included: interoperable object models; interoperable, distributed object architectures; heterogeneous, extended transaction models; and information requests in HAD environments. The group experimented in these areas using the prototype DOM system that it developed over five years. This technology was based on ideas from a number of technical areas including distributed, object-oriented, databases, multi-database systems, operating systems, and programming languages.

The following technical reports (TR) were produced by the DOM group. References are given for those that have been published and the TR designation has been removed. Some reports are marked as [not available], the remainder have not been published other than as GTE Technical Reports and are available in the ACM SIGMOD Anthology.
